The purpose of this study is to report the factors of circulatory disturbances in the fingers of baseball players and the symptoms of those and to investigate the incidences by the administration of a questionnaire. The respondents were 804 players belonging to clubs in junior high school, high school, and universities. According to questionnaires, 202 players (25.1%) were aware of circulatory disturbances in their fingers, and there were most replies having circulatory disturbances in the catching hand with index finger. Especially players of a position with much catching balls frequency, such as a catcher and a first baseman, seem to have the high rate of having circulatory disturbances from repetitive ball impact. No relation to their positions, the appearances of circulatory disturbances in the fingers was remarkably increased from 4 to 7 years from beginning baseball that suggested this period would be needed the device and the measure of practice method for prevent or relief from repetitive ball impact. The various factors seem to be relative causing the appearances of circulatory disturbances in the fingers, such as years of experience playing baseball, their position, their using globes or mitts, temperature, ground condition, smoking custom and so on.

The purpose of this study is to report "the circulatory disturbances in the fingers of baseball players", and to analyze those of the tendency and the rate of incidences as each area by the administration of a questionnaire. It also researches the influences of external environments of the position, the practice, and the temperature and so on. The questionnaires were conducted on 274 players belong to the baseball club of 6 high school attached to Tokai University. According to questionnaires, 76 players (27.7%) were aware of circulatory disturbances in their fingers. The circulatory disturbances in the fingers is caused by the hyperextension of the throwing fingers as the repetition of throwing performance and the mechanical stress of catching the ball as the repetition of catching performance. As a characteristic of positions, the catchers and the infielders tend to be aware a tingling and numbness in their catching index fingers, the pitchers throw with index and middle fingers. The various factors such as their position, practice time, teaching technique seem to be relative causing the appearances of circulatory disturbances in the fingers, but air temperature didn't seem to be related.

The purpose of this study is to investigate the effect of artificial carbon dioxide-rich water for peripheral circulatory improvement on fingers of baseball players with circulatory disturbances catching hands with index fingers suffering from repetitive ball impact. A trial therapy of bathing in artificial carbon dioxide-rich water and fresh water for following the nine university baseball players having symptoms of circulatory disturbances graphic evaluation of thermograph and analysis of temperature on fixed point was done. Results suggest circulatory improvement of fingers : two players of the artificial carbon dioxide-rich water tended toward increased temperature on their catching hands, indicating improved blood flow in the index finger and center-point of the palm area. The measurement conditions were not always ideal because there were some variance in this trial therapy, for example environmental temperatures, degrees of circulatory disturbances, problem progress of bathing and so on ; nevertheless treatments for circulatory disturbances in the fingers under the condition of low temperature don't currently exist. The therapy of bathing in artificial carbon dioxide-rich water seems to be useful on the sports field.
